Hi all, This is a minor update to V4.
Firstly it updates the diagnostics for versioned function decls to include the target_version/target_clones attribute, and simplified the diagnostic logic changes in cpp/c frontends. Secondly, I merged this series with my C FMV support series and my FMV inlining optimization patch. It proved keeping 3 patch series in sync was more bother than it was worth. Kind regards, Alfie Richards Change log ========== V5: - Merged patch series with C support series, and FMV call inlining optimization - Addressed Jason's feedback and simplified the diagnostics for FMV. V4: https://gcc.gnu.org/pipermail/gcc-patches/2025-April/681047.html - Changed version_info structure to be sorted by priority - Split the target_clones pass into early/late stages - Split out fix for PR c++/119498 V3: https://gcc.gnu.org/pipermail/gcc-patches/2025-March/679488.html - Added reject target_clones version logic and hook - Added pretty print for string_slice - Refactored merging and conflict logic in front end - Improved diagnostics V2: https://gcc.gnu.org/pipermail/gcc-patches/2025-February/675960.html - Changed recording of assembly name to be done in version into initialisation - Changed behaviour for a lone default decl V1: https://gcc.gnu.org/pipermail/gcc-patches/2025-February/674973.html - Initial Alfie Richards (22): Add string_slice class. Remove unnecessary `record` argument from maybe_version_functions. Update is_function_default_version to work with target_version. Refactor record_function_versions. Change make_attribute to take string_slice. Add get_clone_versions and get_target_version functions. Add assembler_name to cgraph_function_version_info. Add dispatcher_resolver_function and is_target_clone flags to cgraph_node. Add clone_identifier function. fmv: i386: Refactor FMV name mangling. riscv: Refactor riscv target parsing to take string_slice. fmv: Add reject_target_clone hook for filtering target_clone versions. fmv: Change target_version semantics to follow ACLE specification. c/c++: Add target_[version/clones] to decl diagnostics formatting. c++: Refactor FMV frontend conflict and merging logic and hooks. fmv: Support mixing of target_clones and target_version. c++: Fix FMV return type ambiguation aarch64: testsuite: Add diagnostic tests for Aarch64 FMV. aarch64: Remove FMV beta warning. c: Add target_version attribute support. c/aarch64: Add FMV diagnostic tests.
